Navigating snowy or icy roads is not the time to be wondering about the difference between snow tires and regular tires. Give your tires some thought before winter weather hits!
The right tires can improve the safety and performance of your vehicle. Firestone Complete Auto Care, the nation’s leading tire provider for more than a century, is here to explain the difference between snow tires and regular tires, and help you determine which tires are right for your vehicle when the temperature drops.
Snow Tires Are Designed for Winter
Snow tires are uniquely designed to improve traction in snowy and icy conditions. Regular tires are not. There are three main features that set winter tires apart from regular tires: rubber composition, tread depth and pattern, and biting edges.
- Rubber Composition: Winter tires are made with a special rubber that works best in cold temperatures. The rubber is designed to stay soft and pliable when the weather cools so your tires can maintain adequate grip and traction. The rubber in regular tires (even all-season tires) stiffens in the cold, which reduces traction.
- Tread Depth and Pattern: Winter tires have deeper tread depths than regular tires, especially performance tires. Deeper tread depths improve traction in the snow and lessen snow buildup. In addition to deep treads, winter tires also have unique tread patterns, or grooves. These special grooves help prevent hydroplaning by efficiently pumping water through the tread. Moisture is essentially pushed out and away from the tire so your wheel can make solid contact with dry ground.
- Biting Edges: Winter tires have a series of zig-zag grooves covering their tread. And you guessed it! Regular tires do not. These grooves act as biting edges to grip the road in snow or ice. Watch this video about Blizzak winter tire technology to learn more about biting edges!
Sure, features like all-wheel-drive, anti-lock braking, and traction control help make the most of your vehicle’s available traction, but they don’t create traction. That’s your tires’ job. Specially designed snow tires work with the other features of your car to combat the combination of cold temperatures, ice, and snow.
Consumer Reports agrees! They report, “Our test-track observations lead us to advise that using snow tires provides the best grip and assurance for going, stopping, and cornering no matter what you drive: all-wheel drive, front-drive, or rear-drive.”
Regular Tires Won’t Cut It in the Cold
Why aren’t regular tires up to the task of protecting you and your car in wintry weather?
As we mentioned earlier, colder temperatures cause the tread rubber of a regular tire to get stiffer and less able to conform to the irregularities of even a dry road. When you add ice and snow to the mix, regular tires have an even harder time gaining traction because the road’s irregularities are now filled in and smoothed over by the snow and ice.
Also, when a frozen surface of ice and snow comes under pressure from a tire rolling across it, heat and friction melt the surface of the ice and produce a thin film of water. This water film makes icy roads especially slippery.
Another thing that makes roads slippery? Slush. When the air temperature exceeds 32°F, the surface of the ice gets slushy. As the water film and slush deepen, your tires’ grip gets worse, making slippage more likely.
When you’re faced with these tough winter road conditions, a regular tire won’t give you the same grip and handling that a snow tire could.
Snow Tires Aren’t Right for Every Driver
If temperatures in your area aren’t in that range, then winter tires might not be right for your vehicle. The winter tire experts at your local Firestone Complete Auto Care can help you choose which option is best for your vehicle.
Keep in mind that winter tires shouldn’t be used in the summer months, since the tires’ compounds might be susceptible to rapid treadwear. Also, winter tires should be installed on all wheels, not just the back or front axle.
